A 2 part presentation, Pi Essentials, always good to know. And using DNSMasq to DNS-up your house (never think in numbers again)
Pi Essentials will be a beginner level introduction to some of the things you can (or maybe should) do when the Pi starts up. Nothing requires more than a few lines of code, and these are the sort of add-ons that can go with your main project. Included are buttons to put the Pi in standby mode, and start it running again, and pilot lights to show whether or not the Pi is running. A sound notification at start-up using simple text to speech, and how to put an icon on the desktop that can be clicked on to start your program are also included. The way these utilities are organized and documented will illustrate one method of keeping track of your SD card contents.
We are back at Quality Foods, View Royal, 27 Helmcken Rd #110
Naturally, you can run PiOS on your Raspberry Pi, but are there other options, which have a full GUI (XFCE). Turns out, you can run Alpine Linux with full GUI on the Pi. A lighter-weight distro, which also doesn’t require systems.
Why just run your own video conferencing server, when you can simultaneously run that AND mail, calendaring, contacts, calls, IM, file sharing, remote backup, and a web-based office suite, all in one intimidating package. Get your own thrift-store Google G Suite going with the open source Nextcloud platform on a tiny Raspberry Pi! Great for the privacy-conscious, the independent, and masochists. We’ll do it the hard way and make configuring Jitsi look like recess at kindergarten (and then do it the easy way). Warning: the hard way will race through dependencies including Apache, PHP, MySQL/MariaDB and openSSL, so expect some mild suffering.
I have been playing with Galene for over a year. And have been using it on a weekly basis to do video conferencing with some friends in Ottawa. It is much easier to install than Jitsi, but lacks some of the finer points of jitsi.
Still, you can install and run it on a Raspberry Pi (even a 3b+ !). In this presentation, I’ll show how easy it is to install on a Pi, and you can run your own personal video conferencing server.
We will be having a discussion about Projects that we are working on, but haven’t shared with the group. These can be projects that are successful or ones that just didn’t work out and have been abandoned. We’ll enjoy hearing about other’s projects, and perhaps even offer to help.
NetSIG is a Special Interest Group focused on computer networking. Building networks for Today and Tomorrow!
Last month we explored MACVLAN interfaces, and how it makes it easier for Linux Containers (LXD).
This month, BRING YOUR PI, and a 32 GB SD Card, and we’ll do a Linux Containers INSTALL FEST on your Pi.
We will be meeting in-person at Quality Foods (small boardroom upstairs), bring a laptop and have Wireshark installed. This will be hands on. PLEASE BRING an ETHERNET dongle/port as we will be ssh-ing into your Pi, and configuring Linux Containers.
In this session, we’ll demo the Go programming language. We’ll review the basics of the language, and how to get started with it. We’ll also look at some of the tools that are available to help you program in Go.
After using Linux Containers (LXD) for a couple of years, Craig will share how to easily get your containers connected to the internet using a MACVLAN interface. No reconfiguration of the host is required. This technique can be used on Pi’s as well as other hosts.
We will set up containers using the MACVLAN network attachment, discuss limitations, and even run LXDware, a web-based GUI for LXD on a Pi.
We will be holding a Hybrid meeting (in-person & Jitsi).
Jim will cover the details of Infra-Red Communications, including basic components (emitter & receiver), data encoding methods, external components & software, how to generate pulses, and how to receive pulses on the Pi Pico.
